This invention relates to concealed hinges and particularly'to hinges ofthis class employing two substantially similar sheet metal buttmembers,coupled together by one or more link members, and particularly to hingebu ts of this class adapted to be mounted in cylindrical orsubstantially cy lindrical apertures in the stationary support andswinging member, respectively; and the object ,of'the invention is toconstruct the hinge butts from a sheet metal blank fashioned to form achannel portion which traverses the bone or aperturein which the butt ismounted, and toprovide at the outer end of said ,channel ,bqdy,laterally extending flanges fashioned to form closures for the aperturesor sockets which the butts are mounted; a further object being toprovide a hinge butt of the class described, which by virtue of theconstriction employed, may be manufactured at a nominal cost and yetprovide a strong and durable hinge butt con struction, an especially inthe construction of small hinges such as used in cabinet work; a stillfurther object being to provide means for reinforcing the butt and toprovide channels therein for guiding the movable link or link membersemployed; and with these and other objects in view, the inventionconsists in a hinge butt vof the class and for the purpose specitiedwhich is simple in construction, efficient in use, and which isconstructed as hereinafter described and claimed.

The invention described and claimed herein is an improvement .on thatshown and described in 'a prior application filed by me November 27,1925, and bearing Serial No. 71,539, and is fully disclosed in thefollowing specification, of which the accompanying drawing forms a part,in which the separate parts of my improvement are .designated bysuitable reference characters in each of the views, and in Which:

Fig. 1 is an edge view of a stationary sup- .port "and swinging membershowing my 1m" proved hinge mounted in connection there-v with.

2 is a partial section on the line 22 of Fig. 1.

Fig. 5 is a partial section on the line 5-5 ,ofliigQyan, i i i Fig; 6 isa view similar .to, Fig. 5 but showmg a modified form of construction fI In the drawing, 1 have shown at 10 and 11,

partial section on the line a stationary supportancl swingingmember,

the edge of ,each of which'is providedwith an aperture or socket 152for' rciving tghe separate butts of my improved hinge .1 3. In theconstruction shown in Eig sfl {5615 inclusive, each ofthe butts isfashioned from a sheet metal blank 14 ,sho'wn in' Fig. 310i the drawing,one side edge of the blank being cut out to form a recess 15, to form atthe opposite sides of said recess, arc-Shaped portions 16 foldable,onthe -171atright i angles ,to the longit nal plane ioli' the sheet.The blank Mus also folded on the lines 18 to bring the side portions 19and 20 thereof into parallel relation to form of theblank,

a vi f apfigl ch nel butt bo y, h bsshead 21 ot which is arc-shaped interm to the curvature of the walls Tot the recesses or aperture 12, asclearly seen ,in Fig. 5l'of the drawing. The crossliead preferablyotfset a 01 r ta s e 'a 2 t 159 11 a i n r'ving and strengtheningdrib.or corrugation.

The s d hiembs and 2 a e pm ided on their inner and adjacent faces withare sha ed grooves 2.3 f rmed by Pressing t metal outwardlyin U orchannel fashion as i seen at 241 in ig. 5 of {the drawing. The outwardlypressed channel ermanent also form ribs which aidstrengtheningorreinforcin g the side members Qor bearing plates 19 and20 ofithe separate buttsof the hinge.

The grooves 23 ,open through" the inner or lower ends of the butts .as''lclearly seen in Figs. 2 and 3 of the drawing 1 facilitate the mountingof ,pins12 5 in said g QOVQs. The pins 25 'are mounted upon andcarriedby the free end portions ,of links 26 substan- 7 'tially J-shaped inform, vsaid links being shown are in alternate arrangement; that is tosay, the long arm of one link is movable in the channel or groove 23 ofone butt, and the short arm thereof pivoted on the pin 28 in the otherbutt, and the next adjacent link is alternately arranged; that is tosay, the short arm is pivoted in the first named butt and the long armmovable in the second' named but-t as is the common structure ininvisible hinges of the class under consideration.

In Fig. 6 of the drawing, I have shown a slight modification, whereinthe crosshead portion of the body is enlarged as seen at 30 to give agreater bearing for the butt in the socket or aperture 12; while thefront or free edges of the side portions of the butt have outwardlyturned and curved flanges 31 which rovide a greater bearing surface forthe utt in the socket 12, and also serve to reinforce and strengthen thefront edges of said side. portions. In this form of construction, I alsosubstitute for the grooves 23 and arc-shaped ribs 24:, formed by saidgrooves, apertures 33 in the opposite side walls of the hinge butt, andin the same arrangement as the grooves 23, it being understood that thepins 25 of the links 26 operate in the apertures 33. Aside from themodified features above stated, the butt shown in Fig. 6 will be of thesame construction as that shown in the other figures of the drawing. I

The separate side ortions 19 and 20 of the butt are prefera ly providedat their inner edges with prongs 32 which are preferably placedlaterally and adapted to be driven into the base of the sockets orapertures 12, as seen in Figs. 2 and 4 of the drawing. When the buttsare mounted in position, the wings or flanges 16 form closures'for thesockets or apertures 12 as clear- 1y seen in Figs. 1 and 2 of thedrawing, and preferably seat within said socket so that the outer facesof the parts 16 lie flush with the outer faces or edges of thestationary support and swinging member 10 and 11. W'ith the type ofhinge construction shown, it will be understood that the adjacent edgesof the stationar support and swinging member may be brought intoabutting relation by moving the swinging member into closed position, inwhich position, the links 26 are contained within the respective buttsof the hinge, and the swinging member may be moved into a fully openposition as seen in Flgs. 1 and 2 of the drawing;

By constructing the hinge butts in the manner herein shown anddescribed, it will be apparent that a strong and durable butt may beproduced in a simple, quick and economical manner, and withcomparatively few bending, forming and other operations, whereby a hingeof the class described may be produced at a very nominal cost, and

especially hinges of this type for light duty such as for use incabinets and the like.

While I have shown certain details of construction for carrying myinvention into effect, it will be understood that various v changes inand modifications of the construction herein shown and described, may bemade within the scope of the appended claims without departing from thespirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new an desire tosecure by Letters Patent, is

A sheet metal hinge butt comprising a U-shaped body and laterallyextending flanges at one side of the arms of said body, the oppositewalls formed by the arms of said body having apertures for receiving thelink pivot pin of the hinge, said walls being provided 011 adjacentfaces with grooves for guiding a link of of the hinge in its movement insaid butt, and means for reinforcing the crosshead of said body.

2. A sheet metal hinge butt comprising a U-shaped body and laterallyextending flanges at one side of the arms of said body, the oppositewalls formed by the arms of said body having apertures for receiving thelink pivot pin of the hinge, said walls being provided on adjacent faceswith grooves for guiding a link of the hinge in its movement in saidbutt, means for reinforcing the crosshead of said body, and said groovesbeing formed by pressing the body of the butt outwardly, forming ribmembers for reinforcing the walls of said butt. 3. A hinge butt formounting in a cylindrical socket formed in a workpiece, comprising abutt body of a length substantially equal to the depth of the socket,the width of said body being such as to engage opposite walls of saidsocket and to form chambers in the socket at the opposite sides of thebutt body when mounted therein, and means at the outer end of the buttbody for closing said chambers.
